Last time I went to Canada and the Customs officer was checking out my pickup/boat.I had no firearms with me.I did have an empty CCI 22 Mini-mag plastic ammo box visible,the intent being to put small terminal fishing tackle in it.Customs agent's hand goes to sidearm.I very slowly,carefully showed her it was empty,I was recycling a plastic box that was useful.

Another agent comes over.After about the third"Do you have any weapons?"
I told them I had a machete in the truck but I considered it a tool rather than a weapon.
